    Investment casting is basically a metal shaping technique. It is a foundry practice by which high precision castings are manufactured. This is a specialized foundry technology and is considered a high - tech area; this process has gained popularity on the basis of the superior quality of the castings produced. In addition, more important is the fact that, the cost of a finished component produced by the investment casting process is less than or comparable to that of the conventional production techniques.
    The castings allow the production of components with accuracy, repeatability, versatility and integrity in a variety of metals and high-performance alloys. There are a variety of materials that can be used for the investment casting process, including stainless steel alloys, brass, aluminum, and carbon steel.

    Advantages of Investment casting :

  • 1. This is a high precision casting technique, hence, near net shapes; very near to the finished component is produced.
  • 2. Machining requirements for the finished component is reduced by up to 90%, substantially reducing machining and scrap cost.
  • 3. The process is extremely versatile; almost any intricate shapes, thin walls and tiny delicate components can be cast. This allows for extreme design flexibility.
  • 4. Excellent surface finish is a major advantage of this process.
  • 5. There are no metallurgical limitations for investment casting. Difficult to machine metals are best shaped by this process.
  • 6. The qualities of investment castings are markedly superior to other casting methods. This is an inherent advantage of the process.
